ChartDirector 6.0 (C++ Edition)

Axis.getMinValue


Usage

double getMinValue() const;

Description

Gets the lower bound of the axis.

The lower bound of an axis is known only after auto-scaling. So this method should be called only after axis layout (after calling XYChart.layoutAxes, BaseChart.layout or XYChart.packPlotArea).

Arguments

None

Return Value

The lower bound of the axis.
